「由斯對法至名剎那法性」者，論主復言。由斯相續立住義故，說一切有部阿毘達磨所說理成。故彼論言「云何名住？謂一切行已生未滅，相續說住，非生已經停不滅名剎那法性。以時極促名一剎那，若更經停，便非極促。論主雖復意朋經部，於本論文不多非撥，故引為證。

Regarding "Due to this, the Abhidharma ... is named the dharma-nature of a moment": the author of the treatise states further. Because the meaning of duration is established by this continuum, what is said in the Sarvāstivāda Abhidharma is logically tenable. Therefore that treatise says: 'What is called duration? It refers to all formations having arisen and not yet ceased; duration is spoken of with respect to the continuum, not that having arisen they linger without ceasing, which is called the dharma-nature of a moment. Because the time is extremely brief, it is called a single moment; if it lingered further, it would not be extremely brief.' Although the author's intention sides with the Sautrāntika, he does not overly repudiate the root treatises; therefore, he cites it as proof.
